【摘要】：采煤业的迅猛发展导致煤矸石不断堆积,由煤矸石山产生的酸性废水污染受到了国内外学者的广泛关注。本文在分析煤矸石山酸性废水特点和环境危害的基础上,针对煤矸石山酸性废水酸度大和重金属含量高的问题,简述了矿山酸性废水处理方法的原理和优缺点,分析了不同处理方法的发展现状和技术瓶颈,为煤矸石山酸性废水处理技术的选择、应用和研发提供了关键参数。最后提出技术的耦合联用、源头的氧化控制和煤矸石的资源化减量将是今后解决煤矸石山酸性废水污染问题的重点发展方向。
[Abstract]:The rapid development of coal mining industry leads to the accumulation of coal gangue, and the acid waste water pollution caused by coal gangue mountain has been widely concerned by domestic and foreign scholars. Based on the analysis of the characteristics and environmental hazards of acidic waste water from coal gangue mountain, aiming at the problems of high acidity and high heavy metal content in acid wastewater of coal gangue mountain, the principle, advantages and disadvantages of the treatment method of acid waste water in mines are briefly described in this paper. The development status and technical bottleneck of different treatment methods were analyzed, which provided the key parameters for the selection, application and research and development of acid wastewater treatment technology of coal gangue mountain. Finally, it is pointed out that the coupling of technology, the control of oxidation at source and the reduction of coal gangue will be the key development directions to solve the problem of acid waste water pollution in coal gangue mountain in the future.
